`To vall (whom t may concern.'` j p J Be it known lthat LEDWIN L. GRAULL, a

citizen of the United States of America, and

a resident of Rochester, in `the county of Monroe and State of New York, have-invented certain new and useful Improvements in Watchmens Service, of which theifollowin@ is a specification. I

ly invention relates in general to an improved system of watchmans service and more speciically to an improved method of supervising the rounds and reports of watchmen in a l( rge plant orcompany by means of certain signals operated by and'controlled over the lines cfa local or privateautomatic telephone system.v

Among the Objects of my invention are to provide an efficient and inexpensive system of watchmans service whichaccurately Y records the time and place of a watchmans report and also allows the rounds ofthe watchman to be varied at will, alsoV to providef a system of absolute supervision of all the watchmen, together with their Asupervisoror chief, land to be able togive-Lto an Oiiicial of a company'all knowledge required of `the accuracy of the variousv reports.

' improvement which-will be ,Other Objects areV to `provide a system of in-,

visual signal and also record on the clock the number of the phone used and also the time that the call is made.` I

I propose to use the principles of my invention in connection with `an automatic private exchange telephone system such .as is well known to the public and to the telephone art and such -as is now installed-in various large factoriesand plants. In ksuch a system there may be `for instance a numberof telephones (say Or `100,) Vwhosenumbers run from 11 to 100, and-in which one of said telephones, preferably t #11, is set .aside for a gate man. whose duties may bevaried. ForV instance, the gatefman is in charge .of all watchmen at .nightfand is provided with -v a` set of visuals; (oneforleach telephonellor at least one for any:telephonenwhichtit is desired .to use for watchmens reports, alsofghe may, keeprecords; in the t day time I of;` the number of calls made from the various lines,

reportl any trouble, answer incoming calls I from the outside manual wfsyst'em, :and any .other'desired'features. 5 v Y f 4 g I The gatemans telephone isgthe easiest number to callis .a one way 'line for incomingxcalls -on1yand multipledinto the banks ofthe connector switches without the usual busy gu'ardlsothatfthere maybe as manyycalls to the 'gateman at one time as the number Yof` connector `switches :will permit, thusfpreventing thershuttingoutof ,the gatemanv from any trouble report caused vby his line being busy.

line v#Qa'and O5 for liner #25 in the connector banks,vwhich numbers are known to only Y gateman to call infon any telephone' whether busy'or idle, as the #04; and the other special numbers have no connection from their private or test contactto the regular test circuit of the'various lines and simply have a con- Y nection `from their `test contacts `throngh a resistance t'obattery; I havelshown only a @portion of the lines of the system and` have rshown none of the central oliice switches eX"- cept the line switches, anylwelll known 95 i a few of the ofcials andwhichl permits the shown a special line#-O0 which: is appor-V tioned to some official and which is provided with an extension telephone #8S whichmay be usedrbythe secretaryy oi'7 the ollicial.- The telephone #O is only for specialcallls direct to the ollicialy and! does not appear in the directory whilethe #88 is in the directory for the ollicialsnumber. The normals f of theseV two linesv arer reversed and when #88 is called only the bellat `#88 will ring; when' #00- is called only they bell 'at #OO will= ring, the bells-being legged' off' to Vopposite sides ofv the lineto ground and the connector adapted tov send out generator? over the'upper wipers The subscribe1"s #0GI and #88y are provided' withintercommunicatingbuz'ze'rs and keys for switching theconnectionfrom- 'one to the other. Y

Below the line #OO ifs`- shown the special -detectaphone set #99v which is placeidinf the Vollice 'of the official. Below the line'v #a99 are;r apair of the regulartelephoneseach having line switchl and lthe regular normals marked4 #Qf and l #25 inl the connector banks; Below `the'normals #2er-F have-shown the special buttfi'n number *04, which is directly multipled' to the line 24 and the specialV butt in# numberv @5^ for callin-'g the may be` given a special butt inl connector which will seize the regular lines whether idleor busy.

In F-ig -2-I have shown-.at Cial visual cab- .inet which is located mythe gate house where it can be watched by the gateman or supervisor. This' cabinetfconsistso at visual signal of special design? for each'v line 'of' the Vw-hen av circuitr is closed through' magnets 5 and G the armature isdrawn to the position shown This Aarmature 7 `is pivotedrat its center and carriesav disc 8y which carriesv a pair .of-numbers such as; 21 andl 4 inv the two lower triangular spaces, and'y the`1 upper triangular space being either red or white. This disc 8 rotates back of a cover which is provided with correspondii'ig triangular openingslso that when? magnets 5' and 6 are operated the disc 8 moves to expose the numbers and the Icolor through `the three triangular openings of' the cover. lAll of the magnets 3 and 4' are connected in series with oneendto battery and the other end lead-A which iscontroiled through springs I2 and' conductor I3 and lineY #25 controlsits visual vthroug'jh springs' 114' and conductor l5.

At Bis shownx the recording clock which I- propose to useinfconnection with this service. Thisclook has a' revolving chartwhich revolves once in 24 hours and whichy isfcut up in quadrants representing the time by radial lines.- The chart is also provided with as many concentric circles leaving'- a space around the chart for each stationI in the system, eaclr circular space being designated #00, #22, etc.- fr magnet is provided for eachI circular space, each having anarmature' adapted to prick the chart on one vertica'lline; The magnet apportioned to't'he line #OO for instance, strikes the' chart in the #O0 line at whatever time ,of d'ay or nightv it may be and `is energized over a branch of the conductor 1l which leads' to theV .TLIOOl visual. Thusv it will be seen that whenever the receiver of any line is removed fromI its hook a vcorrespondingly numbered visual signalk willi be operated before the gatemanI and the chart 'of the time clock will be punched in the space al-` lotted tothat line at the time the receiver' is removed. This clock may be kept in an olicials o'liice,I or in some out of the' way place, and may be used to'checkftheV gatema-ns reporty on watchmansl calls;

z Now it w-illfbe seen that a' watchmans round may be laid out every night in a different manner and that as hel goes4 .his rounds he will report from the telephones by simply removing the receiver or by calling the #ll andy talking to the gateman; In case any visual is' operatedf which should'not be operated'by a watchman, the 'gateman may;v cal-lthe'special butt in number of that line and find out who-iis' talking on that Ytelephone an'd listen for any trouble; Thus, if a watchman is' attacked he may knock down va telephone, and the' gatemair will call' the special numbe1` and may hear what is going on. The oflicial or special detectivemay at any time call the number 98 and listen in at the gate house to hear any conversation that may be carried on therein. I have shown also at J (Fig. l)v a special jack any number of which may be installed at various places in the plant and may be used either by watchmen or special detectives to call #1l in case of trouble or to listen in on the various lines. i

The gatehouse supervisor may be provided with a keyY such asK which may control a riot or alarm signal such as bells Which may be located throughout the plant, and if the gateinan receives a trouble report he will sound the riot call by pressing the key K or by any other. device, and all the watchinen "will immediately call #Il and receive orders to report at thel station where the trouble is located. i

In such systems it is usually the practice to have the incoming lines to the plant from the outside manual system terminate in the gate house and the gateman especially at night will be given the duty of answering incoming manual calls and also establisliing outgoing manual calls.` Or, if some Voi'cial desires outgoing' manual service without the attendant supervision he may call a special .#97 which will connect his line across the terminals of #97 and willk energize relay'20 to throw the bridge 21 across the outgoing manual line at springs" 22 to signal the outside operator.

In case a manual call comesin to thev gateman ,in the' evening vfor some official who is working late, the official may be called over the automatic and told to call :#:98y which connects him Vwith the sensitive detectaphone in the gate house. The gateinan may then place the telephone of the incoming manual line as I haveshown it at #98, that is, with the manual receiver close to the sensitive transmitter and with the manual transmitter close to the sensitive receiver. In this way the oilicial may converse with the outside manual subscriber by means ofrthis improvised but ecient voice current repeater.

It will be seen therefore, that I have provided a very simple, economical and yet highly efficient system of watchmans service and one Y which is very Hexible and which may be conducted in almost any way that a company desires, and that the clock and visual cabinet form a very good check upon each other and are both very simply cont-rolled from the existing telephone system.

Having fully described kand ascertained the features and aspects of my invention, what I consider to be new and desire A'to have protected by Letters Patent will be pointed out-in the appended claims.

` What I claim as my invention is:

l. In a telephone system, lines, means Ji'or extending talking circuits therefrom, a .watchmans supervisory system consisting ot a signal for each line operated when a call is made from .that telephone independent of said talking circuit, together' with a time recording device adapted to record the number of the telephone calling and the time at which the call is made, together withV an att-endants station at which said signals are located, and means whereby said attendant may connect with any calling sta- .tion over which a signal has been operated regardless of its 'busy condition over a path also indepndent of said talking circlock which makes a record of the time y when each signal is operated, together with means comprising special call multiples ot"` p the various lines via which the` attendant may call any line whose visual signal has been operated while the lineis busy, and a telephone syssingle device controlled by the "attendant itor restoring any operated signal. Y

3. In combination with atelephone system having lines and automaticV switches responsive to the removal of the receiver to` extend a connection, a recording clock 'mechanism common to said lines, a disc therefor graduated in hours and minutes and lhaving a circular space thereon for each telephone intersected by lines representing the time, la magnet for each circular space and connections 'from Vthe automatic switch of each telephone line whereby when the receiver of thatline is removed,

one of the magnets allottedj to its use is Y operated to mark said charttoi indicate the station calling and the time of call.

t. In atelephone system, a telephone line Vadapted for use as a watchmans reporting station, said line having an individual line switch for extending the line when the receiver is removed, an operating-magnetfor said switch, a display Vboard having a visual s A signal allotted to said` line, a magnet for operating said signal," a graphic ytime recorder comprising a chart and a marking'v magnet individual to said line,a line relay operated when the receiver is removed on said line, and circuits for all of said y magnets controlled by said lineJ relay.
